backtrace (thread apply all bt full)

gtk+-2.18.0 and gtk+-2.18.1 cause firefox-3.5.3 to crash after logging in to
gmail.com

Specifically, after:
1. creating a new firefox profile
2. installing the extensions https://addons.mozilla.org/en-US/firefox/addon/139
and https://addons.mozilla.org/en-US/firefox/addon/433
3. opening two tabs (gmail.com in one tab and
http://news.bbc.co.uk/2/hi/south_asia/8289200.stm in another tab)
4. restarting firefox (so that it restores the two tabs)
5. logging in to gmail in the first tab

firefox crashes with a SIGBUS or SIGSEGV:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff28ff0ff in IA__g_type_check_instance_cast
(type_instance=0x7fffc637d300, iface_type=140737333860672) at gtype.c:3729

    in gtype.c
Current language:  auto; currently c


But with gtk+-2.16.6 (both with glib-2.20.* and 2.22.1), firefox is stable does
not crash.

Also reported in Gentoo bugzilla at
http://bugs.gentoo.org/show_bug.cgi?id=287687

Backtrace is attached.
Comment 1 Alexandre Rostovtsev 2009-10-12 01:18:26 UTC 
Tried gtk+-2.18.2 and glib-2.20.2; I still get an identical crash with an identical backtrace.
Comment 2 Alexandre Rostovtsev 2009-10-12 02:07:16 UTC 
Tried running firefox with GDK_NATIVE_WINDOWS=1 but I still get the same crash.

This commit causes firefox to segfault soon after opening gmail given the following 2 conditions:
1. a UIM input method is active; and 
2. adobe flash is installed.

Reverting this commit causes firefox to function correctly. Verified with gtk+-2.18.0 and 2.18.3.

I don't think this is a bug in gtk+.  See http://bugs.freedesktop.org/show_bug.cgi?id=25139

Alexandre, could you try the fix (http://bugs.freedesktop.org/attachment.cgi?id=31304) for uim 1.5.6?

It works. With the above patch to uim-1.5.6, and with vanilla gtk+-2.18.3, I do not get any crashes in firefox. Thank you very much for tracking this down.

I am going to resolve this bug as NOTGNOME, since it seems that the error was in uim, not gtk+.
